A Velocity Sensitive Keyboard Scanner designed to be used with the Z180, but may be used with any other microprocessor to build a high performance music keyboard system. This device scans an 8 x 8 matrix of changeover contacts and may be extended up to 192 contacts with a few CMOS ICs to enable a variety of keyboard sizes and manuals to be implemented.
KV64 is suitable for use with the Z180 microprocessor family for low component count, high performance designs. Support code examples in Z80/Z180 assembler are provided on request.
Small quantities for evaluation and one off projects:
